# ReadyOp DT vs E

The clearest difference is rating: E at 5.0 against ReadyOp DT's 3.5. E also leads on monetization model (free vs subscription) and iOS requirement (7.1 vs 13.0). ReadyOp DT's advantage is ratings volume (8 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

E holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: ReadyOp DT has 8 ratings behind it against 1, so its average is the more settled of the two.
